Description

Technical Field

[0001] This utility model relates to the field of polyester filament processing technology, specifically to a flame retardant spraying box for flame-retardant polyester filament. Background Technology

[0002] Polyester filament is a widely used textile raw material in the textile industry. To improve the flame retardant properties of polyester filament, flame retardant treatment is usually performed during the processing of polyester filament. Currently, flame retardant treatment of polyester filament mainly relies on the impregnation method (immersion-drying process). This process has problems such as high consumption of flame retardants, high drying energy consumption, and low production efficiency. For fine materials such as filaments, the impregnation method is prone to uneven distribution of flame retardants, affecting the stability of the final flame retardant effect.

[0003] Currently, there is a lack of flame retardant spraying equipment specifically designed for polyester filaments on the market, while general spraying devices suffer from problems such as coarse atomized particles and filament entanglement. Therefore, we propose a flame retardant spraying box for polyester filaments to solve the above problems. Utility Model Content

A conveying pipe 7 is fixedly sleeved on the inner wall of one side of the middle part of the spraying box body 1. One end of the conveying pipe 7 is fixedly connected to a pump body 8. The pump body 8 is fixedly installed on the storage box 10. The other end of the conveying pipe 7 is fixedly connected to a U-shaped pipe 13. The U-shaped pipe 13 is fixedly installed inside the spraying box body 1, and multiple atomizing nozzles 14 are fixedly installed on opposite ends of the U-shaped pipe 13. A second conveying pipe 12 is fixedly sleeved on the inner wall of the other side of the middle part of the spray box 1. A second pump body 11 is fixedly connected to one end of the second conveying pipe 12. The second pump body 11 is fixedly installed on the storage box 10. The other side of the second conveying pipe 12 is fixedly located inside the spray box 1, and multiple rotary joints 17 are fixedly installed on the second conveying pipe 12. One end of the rotary joint 17 is fixedly connected to one end of the rotating roller 15. The bottom end of the rotating roller 15 is rotatably sleeved with a support strip 16. One end of the support strip 16 is fixedly connected to the inner wall of the spray box 1. The top of the rotating roller 15 is rotatably connected to the top wall of the spray box 1.

[0016] Example 2 Reference Figure 1-4 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. Specifically, one end of the guide ring 6 is fixedly connected to one end of the fixing rod 61, and the other end of the fixing rod 61 is fixedly connected to the top inner wall of the spray box 1. The fixing rod 61 supports and fixes the guide ring 6.

[0017] Specifically, one end of the recycling pipe 9 is fixedly connected to the center of the bottom of the spraying box 1, and the other end of the recycling pipe 9 is fixedly connected to the storage box 10. The bottom of the spraying box 1 is provided with a slope to facilitate the collection of flame retardant.

[0018] Specifically, the rotating rollers 15 are provided in multiple sets, and each set includes two rotating rollers 15. The top of each set of rotating rollers 15 is fixedly sleeved with a transmission gear 5, and the transmission gears 5 of each set of rotating rollers 15 are meshed with each other. The transmission gears 5 are movably located on the top of the spray box 1. The top of one of the rotating rollers 15 in each set is fixedly connected to a worm gear 4, which meshes with a worm 3. The worm 3 is rotatably installed on the top of the spray box 1. One end of the worm 3 is fixedly connected to a reduction motor 2, which is fixedly installed on the top outer wall of the spray box 1.

[0019] Furthermore, the guide ring 6 and the atomizing nozzle 14 are set in a one-to-one correspondence, and the two rotating rollers 15 in each group abut against each other. The abutting position of the two rotating rollers 15 in each group is aligned with the center of the guide ring 6, so that each polyester filament can be completely sprayed.

[0020] Specifically, the bottom of the rotating roller 15 is provided with a conveying cavity 151, and a synthetic fiber sleeve 153 is fixedly sleeved on the bottom of the rotating roller 15. The inner side of the synthetic fiber sleeve 153 is provided with a through hole 152. The through holes 152 are opened at the bottom of the rotating roller 15 and are evenly distributed around the circumference. The length of the rotating roller 15 is parallel to the spraying direction of the atomizing nozzle 14, that is, the rotating roller 15 performs coating work on the area not completely covered by the atomizing nozzle 14.

[0021] The working principle and process are as follows: The storage box 10 is filled with the flame retardant to be sprayed. The polyester filaments to be sprayed enter through an opening on one side of the spray box 1 and exit through an opening on the other side. Figure 3As shown, when passing through the spray box 1, the polyester filament monofilament first passes through the guide ring 6 on the left, then through the U-shaped tube 13. The monofilaments are located between the atomizing nozzles 14 arranged opposite each other. Then, the polyester filament monofilaments pass between a set of rotating rollers 15, that is, between the synthetic fiber sleeves 153 of the two rotating rollers 15, and finally exit from the guide ring 6 on the right. During the spraying operation, pump body 1 8 and pump body 2 11 are powered on to draw flame retardant from the storage tank 10 and deliver it through conveying pipe 1 7 and conveying pipe 2 12 respectively. Conveying pipe 1 7 delivers the flame retardant to the U-shaped tube 13, and finally sprays it towards the polyester filament through the atomizing nozzles 14. The flame retardant delivered by conveying pipe 2 12 passes through the rotary joint 1. 7. The fiber enters the conveying chamber 151 of the rotating roller 15, then passes through the through hole 152 to impregnate the synthetic fiber sleeve 153. The synthetic fiber sleeve 153 is made of chemical fiber blended fiber material. At the same time, the reduction motor 2 is powered on and drives the fixed worm 3 to rotate. The worm 3 drives the meshing worm wheel 4 to rotate. The worm wheel 4 drives the fixed rotating roller 15 to rotate. Each set of rotating rollers 15 rotates synchronously in opposite directions through the transmission gear 5. That is, one rotating roller 15 in each set rotates clockwise and the other rotates counterclockwise. The rotating rollers 15 apply the synthetic fiber sleeve 153 to the polyester filament, which further improves the effect of flame retardant spraying on the polyester filament.
